Game registered to SE Account but cant log in to FF14 related services
So my girlfriend bought the FFXIV complete edition that includes ARR, HW and SB for PS4. She registered it to her Square Enix Account, connected her SE Account to her PSN Account and activated the 30 days playtime on her PSN Account. The problem is, whenever she tries to log in to the Forums, the Lodestone, the Mogstation or the Launcher (The PS4 FF14 launcher of course) it just says that the ID or password are wrong. The ID definitely is right and we already tried resetting the password but it still won't work.
Again: Logging in on the Square Enix Website: https://square-enix-games.com/de_DE works and it shows the PS4 version of the game as being registered to her Account but FF14 related stuff doesn't recognize her log in data.
So on the launcher we press next -> I alread have a SE account -> Then when trying to log in there it says the id or password are wrong even though we use the exact same data to log in on the website
